DETAILED DESCRIPTION

[0033] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0034] Example 1

[0035] A display screen transportation device with safety protection function, such as Figure 1-5As shown, it includes a base 101, a placement box 102 is slidably connected to the upper part of the base 101, and connecting plates 1021 are fixedly connected to the front and rear side walls of the placement box 102. The base 101 and the four corners of the front, back, left and right are fixedly connected with shock-absorbing springs 103. The upper left side wall of the connecting plate 1021 is rotatably connected with a knob 104. The right side of the knob 104 is fixedly connected to the left side of the screw 105. The right side of the screw 105 is rotatably connected to the placement box 102. A protective plate 1051 is fixedly connected to the left side of the placement box 102. A total of five sliding frames 106 with equal spacing are slidably connected in the placement box 102. A sponge pad 107 is fixedly connected to the middle of the sliding frame 106. The anti-collision frame 108 is slidably connected to the right side of the storage box 102, and two sliders 109 are slidably connected to the front and rear side walls of the storage box 102, and the two sliders 109 are respectively located on the upper and lower sides of the screw 105. The middle part of the front side of the sliding frame 106 is rotatably connected to a rotating rod 110, and the slider 109 is rotatably connected to a scissor-type telescopic frame 111. The scissor-type telescopic frame 111 is rotatably connected to the protective plate 1051 and the anti-collision frame 108 at the center rotating shaft, and the scissor-type telescopic frame is rotatably connected to the rotating rod 110 at the leftmost center rotating shaft. The rotating rod 110 is threadedly connected to the screw 105, and a lock buckle 112 is fixedly connected between the front side of the box cover of the storage box 102 and the upper front side of the connecting plate 1021.

[0036] When the display screen needs to be moved, first, the lock 112 on the placement box 102 is opened, the lid of the placement box 102 is opened, and the display screen is placed between the sponge pad 107 and the anti-collision frame 108 on the protective plate 1051 and the sliding frame 106. When the display screen is placed, it is then manually twisted and rotated, and the knob 104 drives the screw rod 105 to rotate, and then drives the rotating rod 110 to move to the left. When the rotating rod 110 moves to the left, it drives the scissor-type telescopic frame 111 to retract to the left, and the angle between the connecting rods of the scissor-type telescopic frame 111 gradually increases. The connecting rods of the scissor-type telescopic frame 111 push the two sliders 109 to move in the upward and downward directions respectively. Since the connecting rods of the scissor-type telescopic frame 111 move to the left to fold, the central rotating shaft in the middle, as the intersection of these connecting rods, will also move closer to the left as the connecting rods are folded, thereby The central axis of the retracted frame 111 drives the sliding frame 106, sponge pad 107, anti-collision frame 108 and other components to move closer to the left side, so that the space between the sliding frame 106, the anti-collision frame 108 and the protective plate 1051 gradually becomes smaller, and the sponge pads 107 between the sliding frames 106 are moved closer to each other. When the sponge pads 107 between the sliding frames 106 are close to each other and fit to the display screen, the space between the sliding frame 106, the anti-collision frame 108 and the protective plate 1051 just fits with the display screen. Then, the cover of the placement box 102 is closed, and the lock 112 is buckled to complete the installation of the display screen. In summary, the sliding frames 106 are driven to move closer to each other by rotating the knob 104, so that flexible adjustment can be made for display screens of different thicknesses, the display screen is protected, and shaking during transportation is prevented, thereby improving the flexibility and safety of transportation.

[0037] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, it also includes a limit plate 201, which is slidably connected to the middle of the bottom of the lid of the placement box 102. The lid of the placement box 102 is fixedly connected to a first telescopic rod 202 that is symmetrically arranged along the lid of the placement box 102. The telescopic end of the first telescopic rod 202 is fixedly connected to the limit plate 201, and a latch tooth 203 is fixedly connected to the middle of the top of the sliding frame 106. The limit plate 201 has a number of limit teeth evenly distributed at equal distances, and the limit teeth of the limit plate 201 are snap-fitted with the latch teeth 203.

[0038] When the display screen needs to be removed after the transport is completed, the lid of the placement box 102 is opened, and the lid of the placement box 102 drives the limit plate 201 and the first telescopic rod 202 to disengage from the tooth 203, and the first telescopic rod 202 is deformed and reset. In summary, through the cooperation of the limit plate 201 and the tooth 203, the sliding frame 106 is limited during the transport process, thereby improving the stability of the sliding frame 106 in protecting the display screen.

[0039] like Figure 2 , Figure 3 and Figure 8 As shown, a sponge board 301 is also included. The sponge board 301 is fixedly connected to the lower side of the placement box 102. The sponge board 301 is a long L-shaped strip for protecting the corners of the display screen. The lid of the placement box 102 is fixedly connected with an anti-collision pad 302 symmetrically arranged along the front and back of the lid of the placement box 102. The anti-collision pad 302 is concave in shape.

[0040] In order to prevent the corners of the display screen from being bumped during transportation, the specific operations are as follows: first, when the display screen is placed in the placement box 102, the anti-collision pad 302 is placed in the lower part and corners of the display screen, and the concave anti-collision pad 302 is used to protect the lower part and corners of the display screen. When the lid of the placement box 102 is closed, the lid drives the sponge boards 301 on both sides to approach the corners of the display screen. When the lid is closed, the sponge boards 301 on both sides wrap the corners of the display screen for protection. In summary, through the cooperation of the sponge board 301 and the anti-collision pad 302, the four sides of the display screen are protected to prevent bumps.

[0041] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 , Figure 3 , Fig. 9 and Fig.10 As shown, it also includes a fixed cylinder 401, which is fixedly connected to the base 101, a piston rod 402 is slidably connected to the fixed cylinder 401, and the fixed cylinder 401 is fixedly connected to a second telescopic rod 403 symmetrically arranged along the fixed cylinder 401, and an exhaust plate 404 is fixedly connected between the telescopic ends of the second telescopic rod 403 symmetrically arranged on the fixed cylinder 401, and the top of the exhaust plate 404 is in contact with the bottom of the fixed cylinder 401.

[0042] In order to avoid the placement box 102 from colliding with the bottom surface due to manual negligence during transportation, the specific operation is as follows: when the base 101 collides with the bottom surface, the placement box 102 is affected by inertia and the force is reduced, and the shock-absorbing spring 103 is deformed by the force. When the placement box 102 drops, the piston rod 402 is driven to move downward, squeezing the air in the fixed cylinder 401, and the air is discharged from the bottom of the fixed cylinder 401 through the exhaust hole in the middle of the exhaust plate 404. However, since the exhaust hole is small, the high-pressure gas in the fixed cylinder 401 cannot be discharged in time, so that the high-pressure air in the cylinder squeezes the exhaust plate 404, causing the exhaust plate 404 to move downward, and the second telescopic rod 403 is deformed and stretched by the force, so that the exhaust plate 404 is out of contact with the fixed cylinder 401, and the bottom of the fixed cylinder 401 is opened to allow the air to be discharged. After the air is discharged, the second telescopic rod 403 is reset, thereby driving the exhaust plate 404 at the bottom to move upward and reset, and the exhaust plate contacts the bottom of the fixed cylinder 401 again to close. After the inertia of the shock-absorbing spring 103 placing box 102 is offset, the shock-absorbing spring 103 is immediately reset, thereby pushing the placing box 102 to move upward. When the placing box 102 moves upward, the piston rod 402 is driven to move upward. When the piston rod 402 moves upward, the fixed cylinder 401 generates negative pressure due to the increase in the internal space. At the same time, since the exhaust hole of the exhaust plate 404 is small, when the piston rod 402 moves upward, the air cannot be replenished in the fixed cylinder 401 in time and effectively, so that when the piston rod 402 moves upward, the resistance is large, thereby causing the piston rod 402 to rise slowly, thereby realizing the slow rise of the placing box 102, preventing the shock-absorbing spring 103 from resetting quickly, causing the display screen in the placing box 102 to be affected by the rebound force of the shock-absorbing spring 103, and jumping upward to bump. In summary, through the cooperation of the piston rod 402 and the exhaust plate 404, the display screen is protected from shock when facing a bump, and the placing box 102 is reset for a second time to prevent a secondary collision.

[0043] like Figure 1 , Figure 2 , Figure 3 and Fig.11 As shown, it also includes a fixing frame 501 symmetrically arranged along the placement box 102, the fixing frame 501 is fixedly connected to the left and right side walls of the placement box 102, the fixing frame 501 is rotatably connected to the handle 502, and the fixing frame 501 is symmetrically arranged with a limit block 503, the limit block 503 has an arc surface at the bottom, the arc surface is in contact with the handle 502, and the maximum rotation angle of the handle 502 is 90°.

[0044] In order to avoid collision between hands and the placement box 102 during transportation, the specific operation is as follows; when transportation is required, hold the handles 502 on both sides. When the entire transportation device is lifted, the handles 502 are rotated 90° and are limited by the limit block 503. The handles 502 no longer rotate. When the transportation is completed, the handles 502 are released. The handles 502 are affected by gravity and reset. In summary, the handles 502 and the limit blocks 503 usually cooperate to limit the handles 502 within the guidance angle to prevent the hands from colliding with the placement box 102 during transportation, causing discomfort.

[0045] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
